Definitions

  • the invention relates to a reactor for the biological treatment of waste water, comprising a reactor vessel intended to receive support material to which biomass can adhere, which reactor vessel is provided with an inlet for water to be treated and an outlet for treated water.
  • Reactors of this type are known and are intended for fixed bed systems i which the support material is fitted in the system so that it is immobile.
  • fixed bed systems are oxidation beds (trickling filters) for the aerobic treatment of waste water and submerged filters for the anaerobic treatment of wasteb water.
  • oxidation beds trickling filters
  • submerged filters for the anaerobic treatment of wasteb water.
  • aerobic trickling filters to fill the reactor vessel with small pieces o support material in the form of lava fragments, plastic rings or cylin ⁇ ders. It is also known to fill the reactor vessel with packages of corrugated sheeting-like constructions which are fitted staggered relative to one another.
  • a disadvantage of these systems is that they are susceptible to blockage, which is caused by solid particles in the waste water or by excessive growth of biomass or by precipitate formation.
  • the reactor In order to remove a blockage, the reactor has to be completely shut down, the water has to b discharged and the support material has to be removed by hand and replaced by cleaned or fresh support material. It will be obvious that removal of a blockage in this way takes considerable time. In addition, odour problems can arise.
  • the aim of the invention is to overcome this disadvantage and to this en the reactor specified in the preamble is characterised in that a number of module tanks adjoining one another, over which said support material can be distributed, are placed in the reactor vessel, which module tanks can individually be inserted in and removed from the reactor.
  • the modules tanks are fixed at their tops in an easily detachable manner, the tanks can be removed without the water having to flow out of the reactor.
  • a robust, easily detachable anchoring of the module tanks is obtained if the tanks rest, at some distance above the base of the reactor vessel, on supports from which tension anchors extend upwards to above the top of the modules through a slot in clamp plates, each clamp plate pressing on the corners of a number of modules and being detachably fixable by means of a wedge which is inserted through an eye in the upper end of a tension anchor.
  • Planks which are fixed by means of the clamp plates, are preferably placed over the top edges of the module tanks.
  • the flow of water from the inlet via vertical downward and upward flows through the successive module tanks to the outlet can be achieved by means of baffle plates.
  • the invention also relates to a module tank for the abovementioned reactor provided with lifting hooks.
  • Figure 1 shows a top view of a reactor according to the invention.
  • Figure 2 shows a cross-section along the line II-II in Figure 1.
  • Figure 3 shows a cross-section along the line III-III in Figure 1.
  • Figure 4 shows a detail from Figure 3 on a larger scale.
  • Figure 5 shows a perspective view of a module tank to be used in the reactor according to the invention.
  • the reactor shown is intended for the biological treatment of waste water and comprises a reactor vessel 1 which has an inlet 2 for water to be treated and an outlet 3 for treated water and a number of module tanks 4, which adjoin one another and in which support material in the form of lava fragments or plastic rings or cylinders or corrugated sheeting-like packages has been or is fitted.
  • the biomass can adhere to this support material, which mass is needed for the anaerobic or aerobic decomposition of impurities in the water.
  • the module tanks 4 rest on legs 5 - n ⁇ wall supports 6.
  • a rod-shaped tension anchor 7 which is indicated by a broken line in Figures 2 and 3 t extends from each of these legs and wall supports to above the module tanks.
  • An opening is made in the upper end of each tension anchor 7•
  • the tension anchors 7 serve to fix the module tanks at their tops.
  • the upper end of each tension anchor 7 projects through an opening in a clamp plate 9 and wedge 10, which clamps the clamp plate 9 over a number (one, two or four) of corner points of module tanks, is struck through the opening in the upper end of the tension anchor.
  • Planks 11 and 12 can also be laid over the edges of the module tanks. The clamp plates 9 then press onto these planks.
  • each module tank is provided with lifting hooks 13 ( Figure 4) intended for fixing the hoisting cables 14 of a hoist ( Figure 2) .
  • the flow of the water from the inlet 2 to the outlet 3 can be influenced by means of baffle plates 1 and 16.
  • the arrows in Figure 3 indicate the direction of flow.
  • the baffle plates 15 project above the module tanks, whilst the baffle plates 16 project below the module tanks.
  • the invention makes it possible to replace one or a few module tanks by clean module tanks at set times, without removing the water from the reactor vessel.
  • the time for which the reactor is shut down can be kept to a minimum. Because the tanks are fixed at the top, the fixing can easily be undone.

Abstract

Réacteur destiné au traitement biologique des eaux usées. Il comporte une cuve de réacteur (1) destinée à recevoir un matériau de support auquel la biomasse peut se coller, et dotée d'une voie d'entrée (2) d'eau à traiter, et d'une voie de sortie (3) de l'eau traitée. Un certain nombre de réservoirs modulaires contigus (4) est placé dans la cuve de réacteur et le matériau de support est réparti sur ces réservoirs. On peut introduire individuellement lesdits réservoirs modulaires dans le réacteur, et les retirer de celui-ci.
